Let's divide 171394 by 20
We want to figure out the number of times 171394 can be divided by 20.

Moving on to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 20

Moving on to step 2:
20 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 20

Moving on to step 3:
When dividing 171 by 20, we get 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 160 from 171, we get 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 20

Advancing to step 4:
20 can be fit into 113 5 times, resulting in a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 13 after subtracting 100 from 113.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 20

Moving on to step 5:
139 divided by 20 is 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 856.0
The remainder is 19 after subtracting 120 from 139.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 20

Advancing to step 6:
If we divide 194 by 20, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 8569.0
Subtract 180 from 194 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
When dividing 140 by 20, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 8569.7
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8569.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8569.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 8569.7, with a leftover of 0.0.
